1995 Chevrolet Astro

PROBLEM: FONT END SHAKES SO BADLY THAT YOU CAN'T CONTROL THE VEHICLE WHEN BRAKES ARE APPLIED.WHEN APPLYING THE BRAKES AT SPEED OF 40 AND ABOVE THE VEHICLE FRONT END SHAKES SO BADLY THAT YOU HAVE TO TAKE YOUR FOOT OFF THE BRAKES TO KEEP CONTROL OF THE VEHICLE. THIS CAUSES THE STOPPING DISTANCE TO BE EXTENDED FAR GREATER THEN IT SHOULD BE. ALSO THIS SHAKING HAS CAUSED ME TO REPLACE THE IDLER ARMS . IF IT WAS NOT CAUGHT IN TIME THEY WOULD HAVE BROKEN LOOSE, AND TOTAL CONTROL OF THE VEHICLE WOULD BE LOST.(PUT IN SHOP ON THESE DATES FOR SHAKING IN FRONT END WHEN BRAKES ARE APPLIED. THIS STARTED 6/8/98 @29407MILES DEALER RESURFACED FRONT ROTORS COST 73.20. IN SHOP AGAIN 9/4/98 @32946MILES. DEALER RESURFACED ROTORS AGAIN NO CHARGE. SHOP 10/21/98 @34520MILES DEALER REPLACED ROTORS AND IDLER ARMS NO CHARGE. IN SHOP 12/9/98 @36746MILES SHOP NEED REAR BREAKS THAT IS PROBLEM WITH SHAKING IN FRONT END. COST 244.52. IN SHOP 12/11/98 @36750MILES SHAKING AGAIN SHOP RESURFACED ROTORS COST NO CHARGE. IN SHOP 3/23/99 @ 40500MILES SHOP CALLED ON 3/24/99 NEED ROTORS RESURFACED AND TIGHTEN IDLER ARMS, COST UNKNOWN AT THIS TIME. THIS IS A VERY SERIOUS PROBLEM IN THE BREAKING SYSTEM THAT COULD CAUSE SERIOUS INJURY TO ANYBODY ON THE ROAD BECAUSE BEFORE YOU CAN COME TO A COMPLEAT STOP YOU HAVE TO REMOVE YOUR FOOT FROM THE BREAKS AND REAPPLY THE BREAKS AGAIN CAUSING THE BREAKING DISTANCE TO SHORTEN GREATLY. ALSO SINCE THE SHAKING HAS CAUSE THE IDLER ARMES TO BE REPLACE ONCE AND TIGHTEN AGAIN THERE IS KNOW TELLING WHEN THEY WILL BREAK LOOSE AND TOTAL CONTROL OF YOUR STEERING WILL BE LOST. AS YOU CAN SEE THERE IS PATTERN SHOWING FROM THE REPAIR DATES THAT THIS PROBLEM WILL NOT GO AWAY IT JUST COMES BACK AFTER A COUPLE OF THOUSAND MILES. I HAVE NOTICE IN YOUR DATA BASE THAT THERE HAVE BEEN 2 OTHER REPORTED PROBLEMS LIKE MIND. ODI ID 825208 AND ODI ID 805773
